Was showing an old climbing friend (a Mac user) GPSNavX and MacENC (trying to entice him into sailing) and he was quite intrigued. From his climbing background, however, he was wondering if there are also topo maps available that would work with it. USGS maps appear to be in DRG format, which I assume is different than BSB (why can't the gov work together???), and haven't yet found others in BSB. Is there a source? Is there a better Mac option for 'land' navigation?
